COVER ATTACHING CLIP FOR CONTAINERS Filed Sept. 6, 1930 10 V :mvamrrma ATTORNEY Patented Apr. 10, 1934 UNITED STATES PATENT OFFICE to Wheeling Steel W. Va., a corporation Corporation, of Delaware Wheeling,

Application September 6, 1930, Serial No. 480,107

10 Claims.

This invention relates to devices for attaching covers to cans, pails and the like, and more particularly to means for securing in place the removable covers of paint pails and like containers.

One object of the invention is to provide a simple, inexpensive and efficient form of metal clip which may be conveniently applied to a pail or can for securing a cover thereon and which may be readily detached to permit removal of the cover.

A further object is to provide a holding clip for the covers of containers which is adapted to be mounted in attaching position by means of a wrench or other form of tool whereby the requisite closing force may be applied thereto and which may be removed by the use of a suitable form of prying instrument, as a punch, ice pick, or the like.

In describing the invention in detail, reference is herein had to the accompanying drawing, in which- Figure 1 is a top plan view of a paint pail or can, showing the application of my invention;

Figure 2 is an enlarged detail section on line 2--2, Fig. 1, showing the clip as it appears prior to its being forced into attaching relation to the pail and the cover;

Figure 3 is a similar section showing the clip in cover attaching position; v

Figure 4 is anouter side elevation of the clip; and- Figure 5 is a lateral edge view of the same.

Referring to said drawing, 1 designates the body of a can or pail of a common commercial form,

- said body having an outwardly turned rim or terminal roll 2 formed about its upper end, said roll being preferably of the vertically elongated form shown. A cover 3 constitutes a closure for said end, the same having an upwardly and outwardly curved seating flange 4 adapted to overlie the roll 2, a sealing ring or gasket 5 of rubber ordinarily being interposed between said roll 2 and said seating flange 4, as shown.

- rest in closely overlying seated relation to the seating flange 4 of the cover 3 and which, therefore, is arcuately curved to accommodate itself to the contour of said flange. The lower portion 6 of said body is preferably made of relatively reduced width and has its extreme lower end portion bent at an acute angle thereto forming an inwardly and upwardly inclined lip 8. Said lip has at its opposite ends downwardly bent lugs 9 of substantially triangular shape adapted, in the seated cover-retaining position of the clip, to have their forward ends seat against the under side of the rim roll 2 in directly opposing clamping relation to the saddle '7, said ends being arcuately curved to correspond with the curvature of the thereby engaged under portion of said rim roll, as shown at 10 in Fig. 5.

The lip 8 is normally disposed relative to the adjacent portion 6' of the clip body to form an angle 11 of approximately 45 degrees, as shown in Figs. 2 and 5. Thus, when initially applied to the pail and pail cover, said clip occupies substantially the pendent position shown in Fig. 2, wherein the saddle '7 thereof overlies the cover flange 4 and the inner ends 10 of the lugs 9 rest against the vertically elongated rim roll 2 at or adjacent to the lower end of the vertical portion of the outer wall of said roll. To effect seating of the clip in cover securing position, a suitable tool, as an ordinary form of wrench having oppositely disposed jaws, is applied to the clip, one jaw thereof seating upon the saddle 7 and the opposite jaw seating upon the clip at the angle between the body portion 6' and the 11p 8, following which downwardly directed force applied to the wrench handle acts simultaneously to draw the clip downward for depressing the cover flange 4 into gasket compressing position and to thrust the lower end of the clip inwardly to a position wherein the lip 8 takes under the rim roll 2. Additionally, the force applied through the intermediacy of such tool, as aforesaid, effects bending of the metal at the angle 11 between the body 6 and the lip 8, reducing said angle to the Disposed at suitably spaced intervals in the circumference of the said end of the pail is a.

extent that said lip occupies a substantially vertical position with the ends 10 of its lpgs 9 disposed in underlying seated relation to the under side of the rim roll, as is clearly shown in Fig. 3.

To render the clip more readily bendable at the angle 11, a notch or recess 12 of any suitable length may be provided in the metal at said angle, as is most clearly shown in Fig. 4.

The body of the clip is prefer-ably made of slightly bowed form, as shown, thereby to dispose the midlength portion thereof relative to the rim roll to provide an intermediate open space 13 adapted to accommodate the end of a pointed instrument, as an ice pick, employed for prying the clip off, as when removal of the pail cover is desired, the point of such instrument being introducible through a hole 14 provided therefor in said midlength portion of the clip.

What is claimed is l. A device for attaching covers on containers, comprising, in combination with a container having a rim and a cover having a. flange for seating on said rim, said container providing a downwardly facing shoulder exteriorly thereof a metal clip shaped to form a body having at its upper end an inwardly bent saddle adapted to seat upon said cover flange and having at its lower end inwardly and upwardly inclined lugs bendable toward said body under downwardly and inwardly directed force applied to said body into underlying seated relation to said shoulder.

2. The combination with a container having a rim and a cover mounted on said container, said cover having a flange overlying said rim, of a unitary metal clip for attaching said cover to said container, said clip comprising a substantially upright body having its upper end turned inward for seating upon said cover flange, an upwardly and inwardly inclined lip formed on the lower end of said body, and lugs formed on and disposed at right angles to the plane of said lip, said lip being. bendable to dispose said lugs in underlying seated relation to said rim.

3. The combination with a container having a rim and an outwardly projecting downwardly facing shoulder and a cover mounted on said container, said cover having a flange overlying said rim, of a unitary metal clip for attaching said cover to said container, said clip comprising a substantially upright body having its upper end turned inward for seating upon said cover flange, an upwardly and inwardly inclined lip. formed on the lower end of said body, and reinforcing lugs formed on said lip, said lip being adapted to be bent toward said body bydownwardly and inwardly directed force applied to said body into a position wherein. said lugs- 00- cupy underlying seated relation to said rim roll.

4. A device of the character described, comprising a unitary sheet metal clip having its upper end bent to form an inwardly extending saddle portion and having its lower end bent to form an inwardly directed lip disposed at an abrupt angle to its body, and stiffening lugs. disposed at substantially right angles to said lip.

5. A device of the character described, comprising a unitary sheet metal clip having its upper end bent to form an inwardly extending saddle portion and having its lower end bent to form an inwardly directed lip disposed at an abrupt angle to its body, and stiffening lugs formed on opposite ends of said lip, said lip being further bendable relative to said body under downwardly and inwardly directed force applied to the latter to dispose said lugs in upright position.

6. The combination with a container having an outwardly turned rim roll and a cover mounted on said container, said cover having a flange for overlying said rim roll, of a unitary clip for attaching said cover to said container, said clip comprising an approximately upright body having an upper inwardly curved terminal end for seating upon said cover flange and having its lower end bent to form a lip disposed at an acute angle thereto, said lip having formed at opposite ends thereof right-angularly disposed downturned lugs of substantially triangular form and being further bendable at said angle to dispose said lugs in substantially upright position in underlying seated relation to said rim roll.
